Definitions
- Modulation technique The modulation technique or the transmission method used is known as OFDM, which makes frequency resources more efficient.
- FIG. 2 illustrates a flow chart of a method in a source node for transmitting data in an OFDM system according to an embodiment of the disclosure
- a bit in the bitmap is associated with multiple frequency bands, which is quite efficient in a system with large bandwidth. For example, assuming the total number of the available frequency bands in the OFDM system is 100, a bitmap with 25 bits may be defined, where one bit in the bitmap is associated with 4 frequency bands. Thus, a tradeoff between bitmap overhead and traffic load is provided.
- the 8 bits may be set as “1 " and other bits in the bitmap may be set as “0”; or if "TRUE” is used as a valid status, the 8 bits may be set as “TRUE” and other bits in the bitmap may be set as "FALSE”.
- the 8 bits may be set as "0” and other bits in the bitmap may be set as "1 "; or if "FALSE” is used as a valid status, the 8 bits may be set as "FALSE” and other bits in the bitmap may be set as "TRUE”.
- step S401 data are converted from time domain to frequency domain before transmitting the data.
- step S501 data are converted from time domain to frequency domain before transmitting the data.
- step S601 determine a set of frequency bands of available frequency bands on which data are to be received in frequency domain
- the source node in a downlink transmission from a BBU to a RRU, the source node is the BBU and the destination node is a RRU; and in an uplink transmission from a RRU to a BBU, the source node is the RRU and the destination node is a BBU.
- the method of Figure 8 is applied to the case that a RRU is a destination node.
- a set of frequency bands is determined based on the detected information.

Abstract
Dans ses modes de réalisation, la présente invention se rapporte à un procédé mis en œuvre dans un nœud source et adapté pour transmettre des données dans un système OFDM dans lequel des données sont transmises sur des bandes de fréquences, du nœud source à un nœud de destination. Le procédé selon l'invention consiste : à sélectionner un ensemble de bandes de fréquences parmi des bandes de fréquences disponibles dans le système OFDM ; et à transmettre des données dans un domaine fréquentiel sur l'ensemble de bandes de fréquences sélectionné, au nœud de destination. Dans ses modes de réalisation, la présente invention se rapporte d'autre part à un procédé mis en œuvre dans un nœud de destination et adapté pour recevoir des données dans un système OFDM dans lequel des données sont reçues sur des bandes de fréquences, en provenance d'un nœud source. Le procédé selon l'invention consiste : à déterminer un ensemble de bandes de fréquences parmi des bandes de fréquences disponibles sur lesquelles des données doivent être reçues dans un domaine fréquentiel ; et à recevoir les données sur l'ensemble de bandes de fréquences déterminé, en provenance du nœud source. La présente invention se rapporte par ailleurs à des appareils correspondants.
